PIN LESS HINGE.

Application filed June 8, 1917.

To all whom it may concern:

Be it known that we, EDWIN B. HOLDEN and Gnonon L. CLARK, citizens of the United States, and residents of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Pinless Hinge, of which the following is a specification.

This invention has for its object the production of a pinless hinge which is particu larly simple in construction and highly efiicient and durable in use; and which is provided with an especially simple means for normally preventing detachment of one hinge leaf from the other; and the invention consists in the novel features and in the novel combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is an elevation, partly in section, of a hinge embodying our invention.

Figs. 2 and 3 are edge views of the hinge leaves, looking downwardly.

This hinge comprises generally leaves having knuckles projecting from their contiguous edges, the knuckles of the leaves being normally arranged in axial alinement and being separable upon a relative axial movement of one leaf relatively to the other, and means for normally preventing such axial movement.

1 and 2 are respectively the hinge leaves having knuckles 3, 4 on their contiguous edges, the knuckles at being formed with axial and upwardly facing sockets 5, and the knuckles 3 being formed with depending axial projections 6.

The sockets 5 and projections 6 are here shown as conical and having complemental cylindrical portions 7, 8 at the bases of the conical portions. Usually anti-friction means as a ball 9 is located at the bottom of each socket, the conical projection 6 also having a semi-spherical socket 10 in its end in which the ball seats, the arrangement being such that the projections 6 bear lightly against the sides of the conical sockets and prevent binding and also any looseness and rattling. The knuckles 4: extend under the knuckles 3 and the upper knuckle 1 is normally spaced apart from the lower knuckle 3.

The means for normally preventing axial Specification of Letters Patent.

Serial No. 173,549.

displacement of one hinge leaf relatively to the other is normally located in the space between the upper bearing a and the lower knuckle 3 and acts to prevent sufficient relative axial movement of one hinge leaf rela tively to the other to dislodge the projections 6 from the sockets 5. Said means comprises a post or spacer 11 attachable to one of the spaced apart knuckles as the lower knuckle 3 by an endwise movement and terminating short of the other or the upper knuckle 4:, the space between the top of the post and the upper knuckle 4 being sufficient only to permit the detachment of posts but not separation axially of the hinge leaves.

As here shown, the post is provided with a threaded end 12 which screws into the complemental socket in the upper side of the lower knuckle 3.

This post is also provided with a shoulder 13 at its lower end for abutting against the upper face of the lower knuckle 3.

The hinge may be provided with suitable ornamental knobs as 14 at the opposite ends of the axis of the hinge, these knobs having threaded shanks which screw into sockets in the upper face of the upper knuckle 3 and the lower face of the lower knuckle 41.

What we claim is:

1. A hinge comprising leaves formed with knuckles at their contiguous edges, the knuckles of the leaves being formed with complement-a1 axial conical sockets and projections having complemental cylindrical bearing surfaces at the bases of the conical portions of the sockets and projections, the conical and cylindrical faces of the projections substantially fitting the conical and cylindrical walls of the sockets, and means at the bottoms or apices of the sockets for engaging the ends of the projections and supporting one of the leaves in an axial direction and thereby relieving the conical walls of the projections and sockets of some of the weight, substantially as and for the purpose described.

2. A hinge comprising leaves having knuckles which interlock upon an axial movement of one leaf relatively to the other, and movable means independent of the interlocking portions of the knuckles for looking the leaves from axial movement when the knuckles are interlocked, substantially as and for the purpose specified.

8. A hinge comprising leaves having Patented Dec. 30, 1919.

knuckles on their contiguous edges which are normally arranged in alinement and are brought into interlocking engagement by a relative axial movement of the hinge leaves, one of the knuckles of one leaf being spaced apart from one of the knuckles of the other leaf when the knuckles are interlocked, and means arranged in the space between said spaced apart knuckles for preventing sufficient axial movement of one leaf relatively to the other, to disengage the knuckles, said means comprising a movable spacer secured to one of said spaced apart knuckles and terminating near the opposing face of the other of said spaced apart knuckles, substantially as and for the purpose set forth.

a. A hinge comprising leaves having knuckles on their contiguous edges 'which are normally arranged in alinement and are brought into interlocking engagement by a relative axial movement of the hinge leaves, one of the knuckles of one leaf being spaced apart from one of the knuckles of the other leaf when the knuckles are interlocked, and means arranged in the space between said spaced apart knuckles for preventing sufficient axial movement of one leaf relatively to the other to disengage the knuckles, said means comprising a post attachable to one of said spaced apart knuckles by an axial movement and terminating a sufficient distance short of the opposing face 0f the other of said spaced apart knuckles to permit detachment of the post, substantially as and for the purpose described.

5. A hinge comprising leaves formed with knuckles at their contiguous edges, the knuckles of the leaves being formed with axial complemental conical sockets and pr0- jections having complemental cylindrical bearing surfaces at the bases of the conical portions of said sockets and projections, substantially as and for the purpose de scribed.

In testimony whereof, we have hereunto signed our names, at Syracuse, in the county of Onondaga, and State of New York, this 15th day of May, 1917.
